Voltage-Controlled Pulse Width Modulator (PWM) – PWM Signal Generator

Description

This is an easy-to-use voltage-to-PWM converter. The project occupies very little space.  The circuit is built using the versatile silicon timing device LT6992-1 chip. Pulse Width Modulation (PWM) Controlled by Simple 0V to 1V Analog Input, multiturn trimmer potentiometer is provided to adjust the duty cycle 0 to 100 %. The circuit also has provision to set the frequency to 2.65Khz, 7.8Khz, 10.7Khz or 15.7Khz using jumper J1 and J2. Circuit operates with a 5V Supply.  D1 is a power LED, all connections are made easy using the 3 pin male header connector CN1. This is a very useful tool as test gear or to drive various circuits that require a PWM signal. The output frequency is very accurate and steady has 1.7% Maximum Frequency Error. CMOS Output Driver Sources/Sinks 20mA
